test question are not allowed sorry :D

Answer 2

hahaha nope

Answer 3

-_- nnesha read the question xD

Answer 4

read the question green apple guy!!

Answer 5

*girl

Answer 6

set up da system of equations
x+y=20 since the combination of both makes 20 questions and
3x+11y=100 since the tru/false is 3 points each and the multiple choice is 11 points each

Answer 7

thats a bit confusing :(

Answer 8

@Nnesha dont help if you dont want to

Answer 9

x + y = 20
3x + 11y = 100
is this right?

Answer 10

yes where x represents the number of t/f questions and y the number of multiple choice questions

Answer 11

Ah okay thanks :)

Answer 12

HOLD ON
we arent done

Answer 13

now we do the solving

Answer 14

do u know how to solve system of equations?

Answer 15

3(x + y = 20)
3x + 11 y = 100
3x + 3y = 60
3x + 11y = 100
-8y = -40
8y = 40
y = 5

Answer 16

WOW very nice
now plug in y in either equation and solve for x

Answer 17

There are 5 multiple choice questions.
x + 5 = 20
x = 15
There are 15 T/F questions.
